Thanks for those references, Karen. Perhaps Kim Mackey will reply andelaborate on his 90-90 rule, which he mentioned to me some time ago. Basically it means that in order to be effective, homework should beassigned when the teacher feels 90% of the students can successfullyaccomplish 90% of the work. Homework is for consolidation andpractice, not for figuring out what one "didn't get" in class.

I hope my paraphrasing did not distort Mr. Mackey's intent. In asituation such as mine, where many parents insist on a certain minimumof homework, it will take extra diligence on my part to live up to thisrule, I believe. I feel my teaching will benefit.
